NBA's Michael Jordan marries ex-model over weekend

Michael Jordan got married over the weekend, with Tiger Woods, Spike Lee and Patrick Ewing among those attending the NBA Hall of Famer's wedding in Palm Beach, Fla.

Jordan married 35-year-old former model Yvette Prieto on Saturday, manager Estee Portnoy told The Associated Press on Sunday.

The 50-year-old Jordan owns the Charlotte Bobcats.

Nearly 300 guests were present as they exchanged vows. The reception took place at a private golf club in Jupiter designed by Jack Nicklaus. Jordan owns a home near the course.

Entertainment included DJ MC Lyte, singers K'Jon, Robin Thicke and Grammy Award winner Usher and The Source, an 18-piece band.

The six-time NBA champion and Prieto met five years ago and were engaged last December.

Jordan had three children with former wife Juanita Vanoy. The couple's divorce was finalized in December 2006.

How would you change Sony's VAIO T13?

How would you change Sony's VAIO T13?

Sony's VAIO T13 was a sub-$1000 Ultrabook with an eye on the education market. While we were impressed by the results, its low price meant that compromises had to be made -- especially in the keyboard department. In fact, we were saddened to see that it was packing shallow keys and weirdly wide spacing that made it uncomfortable to type on. But if you were one of those back-to-schoolers who bought one, what did you think of it and what would you have changed about it?

Former Ms. magazine editor Mary Thom dies in N.Y. crash

YONKERS, N.Y. (AP) ? Prominent feminist Mary Thom, a writer and former editor of Ms. magazine who also was an avid motorcyclist, crashed while riding on a highway and was killed, her nephew said Saturday. She was 68.

Thom had a passion for riding motorcycles and died riding her 1996 Honda Magna 750 on Friday evening on the Saw Mill River Parkway in Yonkers, just north of New York City, nephew Thom Loubet said.

"The important thing to know about Mary is that she was a major leader of the 70's Feminist movement, but never desired the limelight," Loubet said in an email. "She stayed behind the scenes tirelessly crafting the message and simply making it better."

Thom was one of Ms. magazine's founding members and served as an editor there for about 20 years, leaving in 1992. She also was an author who wrote a book about the history of Ms. and was a co-author, with Suzanne Braun Levine, of an oral history of former congresswoman and activist Bella Abzug.

Most recently, Thom was the editor-in-chief of the Women's Media Center's features department, which produces reports and commentaries by national and international contributors.

Thom, an Akron, Ohio, native, lived for decades in New York City, where she became one of the women's movement's best editors, feminist icon Gloria Steinem said.

"She had a gift for helping people tell their own story, not for helping them sound like others, but helping them find their own voice," Steinem said.

Thom loved baseball, especially the Cleveland Indians, and adored watching Jon Stewart's hit Comedy Central program, "The Daily Show," Loubet said.

Thom is survived by her sister and other relatives.

Her death was first reported by The Journal News. Westchester County police did not immediately return calls seeking comment on the crash.

Kentucky woman ordained as priest by dissident Roman Catholics

John Sommers / Reuters

Ordaining Bishop Bridget Mary Meehan (C) presents Rosemarie Smead (R), a 70-year-old Kentucky woman, to the audience after she was ordained as a Roman Catholic priest during a Celebration of Ordination at St. Andrew's United Church of Christ in Louisville, Kentucky April 27, 2013.

By Sofia Perpetua, NBC News

A dissident Roman Catholic group ordained a 70-year-old woman a priest in Louisville, Kentucky, during a ceremony attended by hundreds on Saturday.

About 150 women from all over the world have been ordained in defiance of the Roman Catholic Church that bans them from becoming priests.

Rosemarie Smead will be starting her own congregation and she told Reuters she is not worried about being excommunicated.

"It is a medieval bullying stick the bishops used to keep control over people and to keep the voices of women silent,? she said. ?I am way beyond letting octogenarian men tell us how to live our lives."

Smead, a former Carmelite nun with a bachelor's in theology and a doctorate in counseling psychology, wept throughout the ceremony.

According to a recent New York Times/CBS News poll, seventy percent of U.S. Catholics believe women should be allowed to be priests.

In a statement last week, Louisville Archbishop Joseph E. Kurtz called the planned ceremony by the Association of Roman Catholic Women Priests a "simulated ordination" in opposition to Catholic teaching.

"The simulation of a sacrament carries very serious penal sanctions in Church law, and Catholics should not support or participate in Saturday's event," Kurtz said.

Taliban start spring Afghan offensive with bombing

KABUL, Afghanistan (AP) ? Taliban insurgents marked the start of their spring offensive on Sunday by claiming responsibility for a remote-controlled roadside bomb blast that killed three police officers.

In past years, spring has marked a significant upsurge in fighting between the Taliban and NATO forces along with their local allies. This fighting season is a key test, as the international coalition is scheduled to hand over security responsibilities to Afghan forces next year.

In Sunday's attack in Ghazni province in southern Afghanistan, a bomb exploded under police vehicles traveling to the district of Zana Khan to take part in a military operation against insurgents, Mohammad Ali Ahmadi, the province's deputy governor, told The Associated Press.

He said the blast destroyed the vehicle carrying Col. Mohammad Hussain, the deputy provincial police chief, killing him and two other officers. Ahmadi said two officers also were wounded in the insurgent operation, which he said clearly targeted Hussain.

Taliban spokesman Zabiullah Mujahid claimed responsibility in an email sent to news media. He called the bombing the first attack in the Taliban spring offensive.

April already has been the deadliest month this year for attacks across the country, where Afghan security forces are increasingly taking the lead on the battlefield in the war that has lasted more than 11 years.

Insurgents have escalated attacks recently in a bid to gain power and influence ahead of next year's presidential election and the planned withdrawal of most U.S. and other foreign combat troops by the end of 2014. U.S.-backed efforts to try to reconcile the Islamic militant movement with the Afghan government are gaining little traction.

There are about 100,000 international troops in Afghanistan, including 66,000 Americans. A top priority of the U.S. force, which is slated to drop to about 32,000 by February 2014, is boosting the strength and confidence of Afghan forces.

Also Sunday, the U.S. Air Force said the coalition plane that crashed on Saturday in southern Afghanistan, killing four service members, was a MC-12 Liberty aircraft.

The twin-engine turboprop plane provides intelligence, surveillance and reconnaissance, or direct support to ground forces. It crashed in Zabul province, about 180 kilometers (110 miles) northeast of Kandahar Air Field, the Air Force statement said.

The four Air Force service members were deployed to the 361st Expeditionary Reconnaissance Squadron with the 451st Air Expeditionary Wing at Kandahar Air Field, the statement said. Their bodies were recovered. The cause of the crash is under investigation, but NATO has said initial reports indicate there was no enemy activity in the area where the plane went down.

Taliban has named its spring offensive after Khalid ibn al-Walid, a companion of Islam's Prophet Muhammad who became a legendary Muslim military commander known as the "Drawn Sword of God." The insurgents said their forces planned to infiltrate enemy ranks to conduct "insider attacks" and target military and diplomatic sites with suicide bombers.

In the eastern province of Nangarhar, two local officials said insurgents attacked a U.S. convoy as it passed through two nearby villages on Sunday and that four Afghan civilians were killed in the crossfire when the soldiers fired back. The U.S.-led international military coalition said it was investigating reports of civilian casualties in the province on Sunday but could not immediately confirm them.

The coalition also said Afghan and foreign forces arrested six insurgents on Sunday ? three in Helmand province, one in Baghlan province and two in Kandahar province. The report said the two taken into custody in Kandahar city included a local Taliban leader who allegedly coordinated assassinations, sniper ambushes and other attacks against coalition and Afghan forces.

Froman, Pritzker in line for U.S. trade and commerce posts: sources

By Jeff Mason

WASHINGTON (Reuters) - President Barack Obama is close to choosing White House deputy national security adviser for international economic affairs Mike Froman to be the next U.S. trade representative, sources familiar with the situation told Reuters.

After a long vetting process, Chicago businesswoman and Obama fundraiser Penny Pritzker is still in line to be nominated as Commerce secretary, the sources said.

The two trade jobs are among the final positions Obama has to fill in his second term cabinet.

Froman was an early frontrunner for USTR but sources told Reuters earlier this year he preferred to stay in his current White House job, which includes the trade portfolio along with energy, development, and international economic issues.

Jeff Zients, the long-time acting White House budget director, then became a top contender for the post, but Obama asked him to stay at the budget office.

Pritzker, the 271st richest American according to Forbes magazine, was Obama's national finance chair in 2008 and his campaign co-chair in 2012. Her personal fortune is worth an estimated $1.85 billion, putting her at the pinnacle of the top 1 percent of American households.

The Stanford University-trained lawyer and business woman is on the board of the Hyatt Hotel Corp, which her uncle Jay Pritzker founded in 1957, two years before she was born.

Health News - Pigment in the eye found to be key between obesity ...

Athens, Ga. - "Eat your veggies" has been an admonition of parents through the ages, but newly published brain research from the University of Georgia provides one of the best reasons why.

Hammond, Billy 2013-v.env

Billy Hammond

Lutein, the organic pigment that gives fruits and vegetables their color, is a powerful antioxidant that concentrates highly in the human brain and retina, particularly in the eye's macular area. Lutein prevents the oxidation of fat in these areas to maintain the health of the brain and eyes while its absence leads to macular degeneration, the leading cause of blindness in the U.S.

This symbiotic relationship is documented in a new study from the Vision Sciences Laboratory in the Franklin College of Arts and Sciences department of psychology published in the journal Nutrients in March.

"For years people have forgotten that our brain, along with the rest of our bodies, is composed of our diet," said Billy Hammond, a UGA professor in the brain and behavioral sciences program and the study's co-author. "Diet and exercise have a very big influence on how the brain ages and many other basic processes that encourage degeneration, and how our brain protects itself from that is by concentrating antioxidants like lutein in these particular areas."

Hammond, who has published extensively on the nutritional issues of vision development and function, says the relationships between body fat, the brain and antioxidants remain very poorly understood, including highly publicized benefits of fatty acids like omega-3.

"Humans are the great symbiotes of nature, and our biology is based on symbiosis with other microorganisms," he explained. "Basic processes like oxidative stress and inflammatory stress occur very largely in the brain, so even these polyunsaturated fatty acids like omega-3 need to co-localize with an antioxidant like lutein."

The wider messages of intuitive connections between diet, function and aging are both long-held truths and among the most difficult to reconcile with modern life, he said.

"From protecting nervous tissue to preventing degenerative conditions in our brain and other organs, diet and vigorous exercise have by far the most influence on preventing late stage diseases as we age as well as making enormous changes to our biology right now," Hammond said.

The full study is available at http://www.mdpi.com/2072-6643/5/3/750. Additional authors are Emily Bovier, a graduate student in the psychology department, and Richard Lewis, a professor in the College of Family and Consumer Sciences.

The Bird That Struts Its Stuff

IRA FLATOW, HOST:

Up next, it's our Video Pick of The Week. And here with me, as always, is our managing editor and correspondent for video, Flora Litchman. Hi, Flora.

FLORA LITCHMAN, BYLINE: Hi, Ira.

FLATOW: You went on a...

(APPLAUSE)

FLATOW: You went on a local expedition for us.

LITCHMAN: I love Salt Lake City.

FLATOW: Yeah.

LITCHMAN: I just want to...

FLATOW: They love you, it sounds like. Tell us about your expedition.

LITCHMAN: We went on an adventure for this week's video pick, and we went looking for a local celebrity. But I actually was hoping to sound check that with you guys, maybe via applause-o-meter. Who in the audience has heard a sage-grouse?

(APPLAUSE)

LITCHMAN: Well, there you go. OK. And who here has seen a sage-grouse strut?

(APPLAUSE)

FLATOW: Whoa...

LITCHMAN: Wow. Pretty good.

Before we get more into this, I want to bring on our sage on sage-grouse. Jason Robinson is the upland game coordinator for the Utah Division of Wildlife Resources. Thanks for joining us today and for being our tour guide for this week's Video Pick.

JASON ROBINSON: Thanks, Flora.

LITCHMAN: Describe what the strut looks like and why these birds do it.

ROBINSON: Well, it's kind of hard to explain, but I'll do my best. Basically a sage-grouse male has a white collar that's really bright. And what it does is they gather on this leks, and a lek is a location where males gather to kind of strut their stuff for the female hens.

And the males dance around a little bit, all puffed out, their tail feathers are all erect; they have very sharp pointy tail feathers, and they have these air sacs on their chest that they fill up with air and they rub their wings against those stiff feathers on the side and puff out to make kind of a unique noise that attracts the females, and hopefully is - makes them successful for mating.

FLORA LICHTMAN, BYLINE: And we have a little clip of the noise of the sage-grouse while it's strutting and puffing up its chest. Can we hear that?

(SOUNDBITE OF SAGE-GROUSE'S PUFFING)

FLATOW: Oh.

LICHTMAN: Oh.

(LAUGHTER)

FLATOW: Can you do that one? Can you do that noise?

ROBINSON: You know, I've been asked several times to do that and I'm not able to.

(LAUGHTER)

FLATOW: This is SCIENCE FRIDAY from NPR.

LICHTMAN: I'm Flora Lichtman.

FLATOW: And I'm Ira Flatow here at Salt Lake City talking about the sage grouse. You went on this expedition to look for one, right? And you found it right in the first - what did you got?

LICHTMAN: Unfortunately, no.

(LAUGHTER)

FLATOW: No?

LICHTMAN: We did not see any sage-grouse despite Jason's excellent effort. We went all over, mountain to mountain, and we were totally unsuccessful. But our viewers...

FLATOW: The good news is...

LICHTMAN: Yeah. The good news is if you go to our website you can see them, thanks to Jason's agency, which has beautiful footage of these birds strutting it around. And they do this every year at this time, right?

ROBINSON: Right. Yeah. So they go to the same locations, year after year, for generations, and so we keep tracked to that information. You know, normally on a good day - we didn't have the best weather, but usually they're pretty predictable when they're going to be there and what times that sort of thing.

LICHTMAN: And these birds are facing some challenges here.

ROBINSON: They are. They're actually a candidate species for listing under the Endangered Species Act. So there's a lot of conservation efforts to try and save sage grouse and keep the populations from declining.

FLATOW: Can I ask you a question? I found interesting - the video is up on our website at sciencefriday.com. And as part of the video - I watched your adventures, it was quite interesting - is - you said that it requires a huge range of area, lot of open space for it to be successful. Why is that? Why does it need so much territory?

ROBINSON: Well, kind of referencing that, sage-grouse are sagebrush obligate. That means they have to have sagebrush in order to exist, but not just a few plants. They need vast landscapes of sagebrush, anywhere from 10 to hundreds of square miles. And the main reason for that is sagebrush is arid. They don't get much precipitation. There's not a whole lot for them to eat so they're adapted to eat the sagebrush. So they need these large expanses to be able to fulfill the life requirements they have.

LICHTMAN: And they can even gain weight over the winter, you said, because they do so well.

ROBINSON: Yeah. So they're so highly adaptive to eating sagebrush, and sagebrush is actually quite nutritious, the leaves, that they can gain weight in the winter if they have enough sagebrush available.

LICHTMAN: So the populations are declining. Why can people still hunt these birds?

ROBINSON: Well, that's actually the question I get asked most often. And it's probably one of the more controversial things surrounding sage grouse. You know, our agency's primary goal and objective is to keep sage-grouse on the landscape. You know, we work very hard doing that.

One of the things to keep in mind is sage grouse (unintelligible) birds, who actually produce more young than will be able to survive. So some of those are going to die of predation, or starvation or other - other factors.

Here in the state of Utah, we actually harvest less than three percent of the total statewide sage grouse population. And one of the benefits that we get from that is we get a lot of data that we wouldn't get otherwise to help us manage the species.

We also have out sporting group, hunters or conservationists, and they're very good conserving species and being advocates for the species. In addition to that it also generates some funds for protection of habit, for hiring biologists to be spokesmen for sage grouse and for conservation.

FLATOW: Mm-hmm. Well, if you want to see Flora's great adventure out there, looking for the sage grouse, it's up on our website at sciencefriday.com. And also it's very funny.

LICHTMAN: Don't miss it - these birds are really striking.

FLATOW: They are. And I've never seen a sage grouse before, and it's really - I'm struck by how beautiful it is and how unusual is to see that. Thanks, Flora.

LICHTMAN: Thanks, Ira.

FLATOW: Thank you, Jason Robinson, for being our tour guide today.

ROBINSON: Thank you.

FLATOW: It's up on our website at sciencefriday.com. That's about all the time we have. And so we want to thank the folks, everybody here at Grand Theatre at Salt Lake Community College, everybody at KUER - your local public radio station - for making it possible for us to be here.

(APPLAUSE)

FLATOW: Thank you. We want to thank all of you out in the audience. It's well-bunch of people here. It's - what a great record for us to set here in Salt Lake City. Thank you all. You all deserved a round of applause to yourself for coming out to see us today.

(APPLAUSE)

FLATOW: And if you missed any part of the program, or would like to see Flora's Video Pick of the Week, it's up there on our website. Also we podcast in this show, we have a Facebook page, we tweet all the time at SCIENCE FRIDAY. @scifri is our handle out there. And also you can take us along to join your - for anything that you carry along in one of those electronic devices that you have. Thank you again for coming out to see us today. We'll be back in New York. Thanks again. I'm Ira Flatow in Salt Lake City.

Did Syria cross Obama's 'red line'?

WASHINGTON (AP) ? The White House declared Thursday that U.S. intelligence indicates Syrian President Bashar Assad has twice used deadly chemical weapons in his country's fierce civil war, a provocative action that would cross President Barack Obama's "red line" for a significant military response. But the administration said the revelation won't immediately change its stance on intervening.

The information, which has been known to the administration and some members of Congress for weeks, isn't solid enough to warrant quick U.S. involvement in the 2-year-old conflict, the White House said. Officials said the assessments were made with "varying degrees of confidence" given the difficulty of information gathering in Syria, though there appeared to be little question within the intelligence community.

As recently as Tuesday, when an Israeli general added to the growing chorus that Assad had used chemical weapons, White House spokesman Jay Carney said the administration was continuing to monitor and investigate but had "not come to the conclusion that there has been that use."

The Syrian civil war has persisted, with an estimated 70,000 dead. Obama has so far resisted pressure, both from Congress and from within his own administration, to arm the Syrian rebels or get involved militarily. He has, however, declared the use of chemical weapons a "game changer" that would have "enormous consequences."

The White House disclosed the new intelligence Thursday in letters to two senators, but had Defense Secretary Chuck Hagel announce it to reporters traveling with him in the United Arab Emirates. The letters were sent in response to questions from senators of both parties who are pressing for more U.S. involvement, and it marked the first time the administration has publicly disclosed evidence of chemical weapons use.

"Our intelligence community does assess, with varying degrees of confidence, that the Syrian regime has used chemical weapons on a small scale in Syria, specifically, the chemical agent sarin," the White House said in the letters, which were signed by Obama's legislative director, Miguel Rodriguez. He went on to write that "given the stakes involved," the U.S. was still seeking "credible and corroborated facts" before deciding how to proceed.

Two congressional officials said the administration has known for weeks ? and has briefed Congress ? that the CIA and other intelligence agencies have evidence of two incidents of sarin gas use.

A U.S. official said intelligence agencies have had indications of chemical weapons use since March and reached the conclusions made public Thursday about two weeks ago. The two incidents are believed to have occurred around March 19 in the Syrian city of Aleppo and suburbs of Damascus, the official said.

The officials commented only on condition of anonymity because they were not authorized to speak publicly by name.

The White House described the attacks as "small scale," but the full extent of the chemical weapons use and resulting casualties was not immediately known.

Even as Assad has ratcheted up the attacks on his own people, Obama has limited U.S. assistance to non-lethal aid, including military-style equipment such as body armor and night vision goggles. However, he has repeatedly said that the use of chemical weapons, or the transfer of the stockpiles to a terrorist organization, would change things.

"That's a red line for us," he said in August. "There would be enormous consequences if we start seeing movement on the chemical weapons front, or the use of chemical weapons. That would change my calculations significantly."

A senior defense official said the White House letters were not an "automatic trigger" for policy decisions on the use of military force. The official alluded to past instances of policy decisions that were based on what turned out to be flawed intelligence, such as the Bush administration's decision to invade Iraq after concluding that Saddam Hussein had weapons of mass destruction, including nuclear weapons.

Lawmakers from both parties sounded less than patient.

Sen. Dick Durbin of Illinois, a member of the Democratic leadership, was asked what should be done about Assad crossing the "red line." He said, "That's up to the commander in chief, but something has to be done."

And Sen. John McCain, R-Ariz., said, "I think it's pretty obvious that that red line has been crossed. Now I hope the administration will consider what we have been recommending now for over two years of this bloodletting and massacre and that is to provide a safe area for the opposition to operate, to establish a no-fly zone and provide weapons to people in the resistance who we trust."

Other lawmakers questioned whether a cautious U.S. response to the newly disclosed intelligence would only strengthen Assad's resolve to keep a grip on power.

"If Assad sees any equivocation on the red line, it will embolden his regime," said House Speaker John Boehner, R-Ohio.

The White House disclosure put the U.S. in line with Britain, France, Israel and Qatar, key allies who have cited evidence of chemical weapons use. The four countries have also been pressing for a more robust response to the conflict.

U.S. commanders have laid out a range of possible options for military involvement in Syria, including establishing a "no-fly zone" or secured area within Syria where citizens could be protected, launching airstrikes by drones and fighter jets or even sending in tens of thousands of ground forces to secure the chemical weapons caches. But the military has made it clear that any action would likely be either with NATO backing or with a coalition of nations similar to what was done in Libya in 2011.

Following the U.S. disclosure, NATO spokeswoman Oana Lungescu said, "There would doubtlessly be a very strong reaction from the international community if there were evidence that chemical weapons had been used."

Ahmad Ramadan, a member of the Syrian National Coalition opposition group's executive body, called the U.S. assertion an "important step," and he said that America had a "moral duty" to follow it with action.

The White House said the current intelligence assessments of sarin use are based in part on "physiological samples." U.S. officials said that could include human tissue, blood or other body materials, in addition to soil samples.

Sarin is an odorless nerve agent that can be used as a gas or a liquid, poisoning people when they breathe it, absorb it through their skin or eyes, or take it in through food or water. In large doses, sarin can cause convulsions, paralysis and death. According to the Centers for Disease Control and Prevention, people usually recover from small doses, which may cause confusion, drooling, excessive sweating, nausea and vomiting.

The Aum Shinrikyo cult used sarin in attacks in the Tokyo subway system in 1995 that killed 12 people and sickened thousands.

The White House said it was still seeking to confirm the "chain of command" that led to the chemical weapons use. But officials said they were confident attacks were initiated by the Assad government, not rebels, given that they see no evidence of Assad losing control of the stockpiles.

The U.S. said the completion of a stalled U.N. investigation would be critical in confirming the use. But it's unclear whether U.N. inspectors will ever be able to conduct a full investigation in areas where there is the most evidence of chemical weapons use.

The Syrian government has so far refused to allow the U.N. experts to go anywhere but Khan al-Assal, where Assad's government maintains the rebels used the deadly agents.

Officials said the U.S. was consulting with allies and looking for other ways to confirm the intelligence assessments.

How trees play role in smog production

Apr. 25, 2013 ? After years of scientific uncertainty and speculation, researchers at the University of North Carolina at Chapel Hill show exactly how trees help create one of society's predominant environmental and health concerns: air pollution.

It has long been known that trees produce and emit isoprene, an abundant molecule in the air known to protect leaves from oxygen damage and temperature fluctuations. However, in 2004, researchers, contrary to popular assumptions, revealed that isoprene was likely involved in the production of particulate matter, tiny particles that can get lodged in lungs, lead to lung cancer and asthma, and damage other tissues, not to mention the environment.

But exactly how was anybody's guess.

Jason Surratt, assistant professor of environmental sciences and engineering at the Gillings School of Global Public Health, now reveals one mechanism by which isoprene contributes to the production of these tiny, potentially health-damaging particles.

The study found that isoprene, once it is chemically altered via exposure to the sun, reacts with human-made nitrogen oxides to create particulate matter. Nitrogen oxides are pollutants created by cars, trucks, aircrafts, coal plants and other large scale sources.

"The work presents a dramatic new wrinkle in the arguments for reducing man-made pollutants worldwide," said Surratt, whose work was published this month in the Proceedings of the National Academy of Sciences. "Isoprene evolved to protect trees and plants, but because of the presence of nitrogen oxides, it is involved in producing this negative effect on health and the environment."

"We certainly can't cut down all the trees," Surratt adds, "but we can work on reducing these man-made emissions to cut down the production of fine particulate matter."

With the precise mechanism now revealed, researchers can plug it into air quality models for better predicting episodes of air pollution and potential effects on earth's climate. The advance would allow researchers and environmental agencies to evaluate and make regulatory decisions that impact public health and climate change.

"We observe nature's quirks, but we must always consider that our actions do have repercussions," said Surratt. "It's the interaction between these natural and man-made emissions that produces this air pollution, smog and fine particulate matter -- and now we know one reason for how it happens."

First vaccine to help control some autism symptoms

Apr. 24, 2013 ? A first-ever vaccine created by University of Guelph researchers for gut bacteria common in autistic children may also help control some autism symptoms.

The groundbreaking study by Brittany Pequegnat and Guelph chemistry professor Mario Monteiro appears this month in the journal Vaccine.

They developed a carbohydrate-based vaccine against the gut bug Clostridium bolteae.

C. bolteae is known to play a role in gastrointestinal disorders, and it often shows up in higher numbers in the GI tracts of autistic children than in those of healthy kids.

More than 90 per cent of children with autism spectrum disorders suffer from chronic, severe gastrointestinal symptoms. Of those, about 75 per cent suffer from diarrhea, according to current literature.

"Little is known about the factors that predispose autistic children to C. bolteae," said Monteiro. Although most infections are handled by some antibiotics, he said, a vaccine would improve current treatment.

"This is the first vaccine designed to control constipation and diarrhea caused by C. bolteae and perhaps control autism-related symptoms associated with this microbe," he said.

Autism cases have increased almost sixfold over the past 20 years, and scientists don't know why. Although many experts point to environmental factors, others have focused on the human gut.

Some researchers believe toxins and/or metabolites produced by gut bacteria, including C. bolteae, may be associated with symptoms and severity of autism, especially regressive autism.

Pequegnat, a master's student, and Monteiro used bacteria grown by Mike Toh, a Guelph PhD student in the lab of microbiology professor Emma Allen-Vercoe.

The new anti- C. bolteae vaccine targets the specific complex polysaccharides, or carbohydrates, on the surface of the bug.

The vaccine effectively raised C. bolteae-specific antibodies in rabbits. Doctors could also use the vaccine-induced antibodies to quickly detect the bug in a clinical setting, said Monteiro.

The vaccine might take more than 10 years to work through preclinical and human trials, and it may take even longer before a drug is ready for market, Monteiro said.

"But this is a significant first step in the design of a multivalent vaccine against several autism-related gut bacteria," he said.

Monteiro has studied sugar-based vaccines for two other gastric pathogens: Campylobacter jejuni, which causes travellers' diarrhea; and Clostridium difficile, which causes antibiotic-associated diarrhea.

The research was supported by the Natural Sciences and Engineering Research Council.

Police: Boston suspects planned to attack New York

FILE - This combination of undated file photos shows Tamerlan Tsarnaev, 26, left, and Dzhokhar Tsarnaev, 19. The FBI says the two brothers are the suspects in the Boston Marathon bombing, and are also responsible for killing an MIT police officer, critically injuring a transit officer in a firefight and throwing explosive devices at police during a getaway attempt in a long night of violence that left Tamerlan dead and Dzhokhar captured, late Friday, April 19, 2013. The ethnic Chechen brothers lived in Dagestan, which borders the Chechnya region in southern Russia. They lived near Boston and had been in the U.S. for about a decade, one of their uncles reported said. Since Monday, Boston has experienced five days of fear, beginning with the marathon bombing attack, an intense manhunt and much uncertainty ending in the death of one suspect and the capture of the other.

(AP) ? The Boston Marathon bombers were headed for New York's Times Square to blow up the rest of their explosives, authorities said Thursday, in what they portrayed as a chilling, spur-of-the-moment scheme that fell apart when the brothers realized the car they had hijacked was low on gas.

"New York City was next on their list of targets," Mayor Michael Bloomberg said.

New York Police Commissioner Raymond Kelly said Dzhokhar Tsarnaev told interrogators from his hospital bed that he and his older brother decided on the spot last Thursday night to drive to New York and launch an attack. In their stolen SUV they had five pipe bombs and a pressure-cooker explosive like the ones that blew up at the marathon, Kelly said.

But when the Tsarnaev brothers stopped at a gas station on the outskirts of Boston, the carjacking victim they were holding hostage escaped and called police, Kelly said. Later that night, police intercepted the brothers in a blazing gunbattle that left 26-year-old Tamerlan Tsarnaev dead.

"We don't know if we would have been able to stop the terrorists had they arrived here from Boston," the mayor said. "We're just thankful that we didn't have to find out that answer."

The news caused New Yorkers to shudder with the thought that the city may have narrowly escaped another terrorist attack, though whether the brothers could have made it to the city is an open question. They were two of the most-wanted men in the world, their faces splashed all over the Internet and TV in surveillance-camera images released by the FBI hours earlier.

Dzhokhar, 19, is charged with carrying out the Boston Marathon bombing April 15 that killed three people and wounded more than 260, and he could get the death penalty. Christina DiIorio-Sterling, a spokeswoman for U.S. Attorney Carmen Ortiz in Boston, would not comment on whether authorities plan to add charges based on the alleged plot to attack New York.

Investigators and lawmakers briefed by the FBI have said the Tsarnaev brothers ? ethnic Chechens from Russia who had lived in the U.S. for about a decade ? were motivated by anger over the U.S. wars in Iraq and Afghanistan.

Based on the younger man's interrogation and other evidence, authorities have said it appears so far that the brothers were radicalized via Islamic jihadi material on the Internet instead of any direct contact with terrorist organizations, but they warned that it is still not certain.

Dzhokhar was interrogated in his hospital room Sunday and Monday over a period of 16 hours without being read his rights to remain silent and have an attorney present. He immediately stopped talking after a magistrate judge and a representative from the U.S. Attorney's office entered the room and gave him his Miranda warning, according to a U.S. law enforcement official and others briefed on the interrogation.

Kelly and the mayor said they were briefed on the New York plot on Wednesday night by the task force investigating the Boston bombing.

Rep. Peter King, R-N.Y., said in a CNN interview that the city should have been told earlier.

"Even though this may or may not have been spontaneous, for all we know there could be other conspirators out there, and the city should have been alerted so it could go into its defensive mode," he said.

Asked about the delay, Bloomberg said: "There's no reason to think the FBI hides anything. The FBI does what they think is appropriate at the time, and you'll have to ask them what they found and what the actual details of the interrogation were. We were not there."

Kelly, citing the interrogations, said that four days after the Boston bombing, the Tsarnaev brothers "planned to travel to Manhattan to detonate their remaining explosives in Times Square."

"They discussed this while driving around in a Mercedes SUV that they hijacked after they shot and killed the officer at MIT," the police commissioner said. "That plan, however, fell apart when they realized that the vehicle they hijacked was low on gas and ordered the driver to stop at a nearby gas station."

A day earlier, Kelly said that Dzhokhar Tsarnaev had talked about coming to New York "to party" after the attack and that there wasn't evidence of a plot against the city. But Kelly said a later interview with the suspect turned up the information.

"He was a lot more lucid and gave more detail in the second interrogation," Kelly said.

Kelly said there was no evidence New York was still a target. But in a show of force, police cruisers with blinking red lights were lined up in the middle of Times Square on Thursday afternoon, and uniformed officers stood shoulder to shoulder.

"Why are they standing like that? This is supposed to make me feel safer?" asked Elisabeth Bennecib, a tourist and legal consultant from Toulouse, France. "It makes me feel more anxious, like something bad is about to happen."

Above the square, an electronic news ticker announced that the Boston Marathon suspects' next target might have been Times Square.

Outside Penn Station, Wayne Harris, a schoolteacher from Queens, said: "We don't know when a terrorist attack will happen next in New York, but it will happen. It didn't happen this time, by the grace of God. God protected us this time."

In 2010, Times Square was targeted with a car bomb that never went off. Pakistani immigrant Faisal Shahzad had planted a bomb in an SUV, but street vendors noticed smoke and it was disabled. Shahzad was arrested as he tried to leave the country and was sentenced to life in prison.

With tens of millions of dollars in federal homeland security funding at stake, Bloomberg and Kelly have repeatedly sought to remind the public that New York remains at the top of terrorists' wish list. They have said the city has been targeted in more than a dozen plots since 9/11.

Kelly said Dzhokhar was photographed in Times Square with friends in April 2012 and was in the city again in November 2012, but "we don't know if those visits were related in any way to what he described as the brothers' spontaneous decision to hit Times Square."

He said the police intelligence division is trying to establish Dzhokhar's movements in the city and determine who might have been with him.

Meanwhile, the Tsarnaev brothers' father said he is leaving Russia for the U.S. in the next day or two, but their mother said she was still thinking it over.

Anzor Tsarnaev has expressed a desire to go to the U.S. to find out what happened with his sons, defend the hospitalized son and, if possible, bring the older son's body back to Russia for burial.

Their mother, Zubeidat Tsarnaeva, who was charged with shoplifting in the U.S. last summer, said she has been assured by lawyers that she would not be arrested, but was still deciding whether to go.

PFT: Moon still sees bias against black QBs

Top NFL Draft prospects stand on the marquee above Radio City Music Hall ahead of the 2013 NFL Draft in New YorkReuters

Here?s a historical look at the way the Bills have systemically ignored QBs in the Draft (and we wonder why they are the way they are).

For the Dolphins, the 12th pick represents the least of the drama, as trade talks on multiple fronts are ongoing.

Retired Patriots mainstay Kevin Faulk has given newcomer Leon Washington permission to wear his No. 33 jersey.

Short-rope coach Rex Ryan might need the Jets to draft a QB to increase his own job security.

The Ravens have multiple options to find some help at LB.

While the Bengals are hopeful of an Andre Smith deal, he?s still unsigned, which puts RT on the needs list.

Tom Reed of the Cleveland Plain Dealer believes finding CB help is the top priority for the Browns.

The Steelers are taking a closer look at character issues during their pre-draft preparations.

Texans RB Arian Foster will have a role in the movie Draft Day, playing a draft prospect.

The Colts needs list is easy: Anything but QB.

Fan voting has chosen the Titans? 15th anniversary logo, which includes a sword and Roman numerals.

The Broncos are hoping for an early run on QBs, to push the guys they want down to them.

Sam Mellinger of the Kansas City Star is coming around to the idea of the Chiefs trading Branden Albert only to draft his replacement.

Before they can worry about a Commitment to Excellence, Raiders GM Reggie McKenzie wants his team to have a commitment to character.

Few teams have a more glaring need to fill than the Chargers all along the offensive line.

Cowboys VP Stephen Jones says it?s a 50-50 chance the team actually uses the 18th pick.

The Giants haven?t drafted a LB in the first round since 1984.

E.J. Manuel, who said the Eagles ?want me pretty bad? is being mentored by former Eagles QB Donovan McNabb.

The Redskins are comfortable with having the night off tonight, since they have their QB position taken care of.

The Bears might want to move down, but they can?t afford to go too low.

Tonight?s the kind of night that could save Lions GM Martin Mayhew?s job.

The Packers worked out RB Cedric Benson yesterday, but no deal appears imminent.

Vikings GM Rick Spielman said his picks are unlikely to be a ?surprise.?

All signs point to the Falcons drafting a CB, whenever they draft.

Panthers owner Jerry Richardson told city leaders he moved a mountain to accommodate the Democratic National Convention, during his plea for public money.

The Saints can doubtless find someone to help their league-worst defense at 15.

You can?t count the Bucs out tonight, though they don?t have a pick at the moment.

Cardinals GM Steve Keim is ready for his chance to sit in the big chair.

The Rams have solid players, they need playmakers, writes Bernie Miklasz of the St. Louis Post-Dispatch.

Everyone anticipates the 49ers making moves tonight and throughout the weekend, and that raises the stakes for GM Trent Baalke.

The Seahawks have made their moves, so they?re sitting back and watching tonight.

Review of Plantronics Voyager Legend UC Headset

?Can you hear me now??

You may remember that line from a wireless-phone company commercial. ?The reason that line is so successful is that we all say it. I?m willing to bet that many of you say that or some version of that question pretty often. We want to make sure we are heard.

This review of the Plantronics Voyager Legend headset is for the entrepreneur on the go, or the small business owner, manager or professional who needs a solid hands-free device with excellent reception and sound clarity. ?And one also looking for time savings and convenience.

Last year, I was part of a Plantronics contest and received a Voyager Legend headset. At the time, I rarely used my mobile phone for important business calls because I could not depend on the other mobile headsets I had tried in the past. That meant?I coordinated most of my meetings when I was absolutely certain I would be in a quiet place with the strongest wireless signal.

Since then, little by little, I started to use the headset. I?m pleased to report that I use a Voyager Legend headset nearly every day now. ?I live on an island and when I go out for the day for business meetings, I have to take a ferry and am often gone for the day. ?So I end up taking a lot of calls when mobile. ?And I worry less about where I?m going to be when it?s time to take an important call.

The Voyager Legend (pictured below)?comes in several flavors ? regular and what is known as ?UC? which stands for Unified Communications .

headset

?

UC is the platform on a user?s computer that allows them to integrate IM, phone calls, video conferencing and more. The Voyager Legend UC headset plugs into your computer with the included USB dongle, letting you take voice and video calls from your computer. The Voyager Legend UC also comes in two variants; one regular and one optimized for Microsoft. The UC version, either one, is $199. The regular Legend (non-UC version) is priced at $99 and this is the one I have.

Both versions of this headset are multi-point, allowing you to have two different mobile phones configured to connect to your headset. ?That means you don?t have to switch headsets to use a different device.

For team members who use multiple devices during the workday, you begin?to see the advantages.

What I really like:

  • The Mute button. On the headset, there is a simple button, but cooler is that the headset announces to you only that the ?mute is on.? Of course, it tells you it is off, too, when you press it again. You can press the mute button on your actual phone, but I like the headset one.
  • The sensor technology (I don?t know exactly how it works, but it is cool): If I put it on my ear as the phone is ringing it will still answer the call. No fumbling about to make the switch. ?If it?s already in my ear, I can use voice commands to answer it or ignore it.
  • On the UC front, not having to manually connect each device you want to switch to, is a time-saving option.

What I would like to see:

  • A universal charger ? the headset has its own proprietary connection. This is the only downside, in my view. To be fair, it is probably pretty hard to fit a micro-USB connection into that tiny space. The good news is that the other end is a standard USB connection so most chargers will accept the USB end, or your laptop can charge it for you.

Although this review is focused on the Voyager Legend, I have to throw in a few good words about another option ? the Calisto speakerphone, also by Plantronics. The Calisto is a portable speaker approximately four inches square by 1.5 inches tall. It can connect to your laptop with a small USB keyfob or via Bluetooth. ?It is powered by a?rechargeable lithium battery (connect it to a USB charger).

I am using the 620 model, optimized for Microsoft Lync and it is wonderful. Seriously. I have used it as a speaker in hotel rooms to play music on my Samsung S3. And I have used it as a speakerphone in my car when I?m not using a headset. It connects very quickly and for those who find that their cell phone speakers are just not enough, this little device is a lifesaver. It comes in its own little neoprene case for $149.95. It is also UC-capable.

Overall, if you find that you want a robust, sophisticated hands-free device, the Voyager Legend headset (UC or regular) is a serious contender.

If you just can?t put something in your ear, or need a speakerphone, look to the elegant little Calisto speakerphone.

Earthquake rocks Afghanistan, felt in Pakistan and India

NEW DELHI (Reuters) - A moderate earthquake hit Afghanistan on Wednesday and was felt as far away as the Indian capital of New Delhi, the latest in a string of tremors to shake Asia in the past week.

The 5.7 magnitude quake was 40 miles deep with an epicenter 16 miles northwest of Jalalabad, Afghanistan, the U.S. Geological Survey said on its website. There were no immediate reports of damage or casualties.

Buildings swayed in the Indian capital New Delhi and people ran into the street in the disputed northern region of Kashmir, where an earthquake killed about 75,000 people in 2005, most on the Pakistan side. Wednesday's tremor was also felt in Pakistan's capital, Islamabad.

Last week, a 6.6 magnitude earthquake killed nearly 200 people in southwest China, a few days after another powerful tremor killed 35 people in Pakistan near the border with Iran.

Virus kills melanoma in animal model, spares normal cells

Apr. 23, 2013 ? Researchers from Yale University School of Medicine have demonstrated that vesicular stomatitis virus (VSV) is highly competent at finding, infecting, and killing human melanoma cells, both in vitro and in animal models, while having little propensity to infect non-cancerous cells.

"If it works as well in humans, this could confer a substantial benefit on patients afflicted with this deadly disease," says Anthony van den Pol, a researcher on the study. The research was published online ahead of print in the Journal of Virology.

Most normal cells resist virus infection by activating antiviral processes that protect nearby cells. "The working hypothesis was that since many cancer cells show a deficient ability to withstand virus infection, maybe a fast-acting virus such as VSV would be able to infect and kill cancer cells before the virus was eliminated by the immune system," says van den Pol. And indeed, the virus was able to selectively infect multiple deadly human melanomas that had been implanted in a mouse model, yet showed little infectivity towards normal mouse cells, he says.

Many different mechanisms are involved in innate immunity, the type of immunity that combats viral infection. van den Pol plans to investigate which specific mechanisms are malfunctioning in cancer cells, knowledge that would be hugely beneficial both in understanding how cancer affects immunity, and in enhancing a virus' ability to target cancer cells, he says.

Melanoma is the most deadly skin cancer. Most melanomas are incurable once they have metastasized into the body. The incidence of melanoma has tripled over the last three decades, and it accounts for approximately 75 percent of skin cancer-related deaths.

U.S. child porn suspect captured after 5 years

WASHINGTON (AP) ? Investigators say Eric Justin Toth's five-year run as a fugitive began when he was fired from his teaching job at a prestigious private school in Washington after being confronted about images of child pornography taken with a school camera in the man's possession.

It ended over the weekend when Nicaraguan authorities, acting on a tip, found him living in that Central American country ? with phony passports, driver's licenses and credit cards, authorities said. The FBI is investigating why Toth was living there and has previously said he may have been advertising as a nanny or tutor while on the lam.

Now, investigators are trying to piece together how he avoided capture even after he was added to the FBI's Most Wanted list, a notorious designation reserved for those considered dangerous criminals and that has featured the likes of Osama bin Laden and Whitey Bulger. Prosecutors are encouraging any other abuse victims to come forward as they proceed with a federal child pornography case against the 31-year-old Toth, who was ordered held without bond during a brief court appearance Tuesday.

"The fact that he is a known child predator and that he's been on the run for five years, we assume that there's potentially other victims in other places that he's been over the past five years," said Valerie Parlave, the head of the FBI's Washington field office.

A federal public defender assigned to Toth didn't immediately return a call seeking comment. Phone listings for possible relatives of Toth either declined to comment or did not return phone messages.

The arrest on Saturday, in a city near Nicaragua's border with Honduras, ended a frustrating international manhunt for the computer-savvy third-grade teacher and former camp counselor.

There were tantalizing clues along the way ? a fake suicide note in Minnesota, an apparent sighting at a shelter in Arizona, a tip that led agents on an extensive search of South America. Yet Toth continued to elude authorities, even as pictures of his bespectacled and sometimes bearded face were featured on news programs, billboards around the country and the FBI's list.

The big break came from a tip last week after a female tourist who encountered Toth in a social setting recognized him and contacted authorities, said FBI spokeswoman Jacqueline Maguire.

Toth first arrived in Nicaragua in October and appeared to have spent at least part of his time there creating false identities and ID documents, police said. When his house was raided, police found passports, driver's licenses and credit cards from three banks, under different names, suggesting he was preparing new false identities to use, said national Police Chief Aminta Granera. Toth was living under an assumed name, authorities said, and the FBI used records of a recent purchase to pinpoint his whereabouts.

Federal prosecutors unsealed a criminal complaint Tuesday charging Toth with possessing and producing child pornography, charges that together carry a maximum 50-year prison sentence. Toth wore a blue jail jumpsuit, his hair considerably longer than in the photographs the FBI had made public, and he spoke softly in response to a judge's perfunctory questions.

Prosecutors revealed no new details of their case in court. But according to the complaint, multiple images of child pornography ? including one video in which Toth allegedly appeared alongside an undressed young boy ? were located in June 2008 on a media card found inside his classroom at Beauvoir, a private elementary school on the grounds of the Washington National Cathedral.

Although "not the most socially adept guy," he was an engaged teacher who helped students think outside the box in math and logic and who even incorporated lessons on why people do or don't do the right things, recalled Michele Booth Cole, whose daughter was in one of Toth's classes.

"He wasn't teaching from the textbook. It was really much more creative and thought-provoking for the kids," said Cole, executive director of Safe Shores ? the DC Children's Advocacy Center, which helps abused children.

The media card with the pornographic images was found in in a box addressed to Toth at the school's address, the complaint says. Although some of the images showed children laughing and playing, others were every parent's nightmare, said Ron Machen, the U.S. Attorney for the District of Columbia.

Those include photographs and videos showing the hand of an adult male fondling a boy, the complaint says. Another video, taken in what appears to be a classroom at the school, shows a man investigators believe to be Toth with an undressed prepubescent boy.

Toth was fired after the images were discovered by fellow school employees and escorted from the school. He disappeared immediately, long before anyone could arrest him.

But there were soon clues that would set agents in motion.

His car was found later that summer in a long-term parking lot at the Minneapolis airport along with a fake suicide note inside that claimed he was going to kill himself in a nearby lake. But no body was found, and investigators concluded it was a ruse.

"Clearly he was trying to throw investigators off at that point," said FBI Special Agent Kyle Loven, an agency spokesman in Minneapolis.

He was believed to have been sighted in Phoenix in 2009, apparently working as a quasi-counselor at a shelter under an assumed name, the FBI has said. He was gone before agents could get to him.

Authorities also believe Toth, who is from the Midwest, traveled while on the run to Illinois, Indiana, Wisconsin and Minnesota.

In April 2012, the FBI, concerned that the trail was going cold and that Toth's experience in interacting with children and earning their trust might be putting other kids at risk, announced that it was adding him to the bureau's Most Wanted fugitives list, where he filled a slot left vacant by the death of bin Laden.

Ron Hosko, then the special agent in charge of the criminal division of the FBI's Washington field office, said at the time, "This is a dangerous person because of his nature, because he is a child predator, because of his ability to groom both adults and potentially these children to develop some sorts of bond of trust."

Activists fear large death toll near Damascus

BEIRUT (AP) ? Two Syrian activist groups say they fear the past six days of clashes in two Damascus suburbs may have killed hundreds of people.

The Britain-based Syrian Observatory for Human Rights says the number of dead could be as high as 250.

Rami Abdul-Rahman, who heads the Observatory, says the group has documented 80 names of those killed in Jdaidet Artouz and Jdaidet al-Fadel suburbs.

The Local Coordination Committees, another activist group, says the death toll is 483. It says most of the people were killed in Jdaidet Artouz.

State-run news agency SANA said Syrian troops "inflicted heavy losses" on the rebels in the suburbs.

Monday's reports came as President Bashar Assad's forces continued a major offensive in the suburbs against opposition fighters who were closing in on parts of Damascus.
